No decoding of POCSAG

After a hardware crash I changed my hardware to a raspberry 3.0B+ with raspbian on it and did a new installation of RTL_FM and MultiMon-NG . I tried a few days to get multimon-ng to work. The RTL-SDR USB-Stick is the same, rtl_fm puts out a sound a the specified frequency (checked by piping it to aplay) but when i pipe the signal to multimon-ng to decode POCSAG512 and POCSAG1200 nothing happens.
Piping the output from rtl_fm to multimon-ng without defining a protocol to decode, it opens a window an shows the received frequencies (normally a signal noise). If data is send, I can see the different data signal (no noise), but multimon-ng does not decode anything. I then installed the programs on an other PC with Debian on it, but the result was the same. Receiving with rtl_fm works, pocsag decoding with multimon-ng fails.
I started the decoding in the terminal with "rtm_fm -f 170.150M -g 50 -l 70 -s 22050 - | multimon-ng -t raw -a POCSAG512 -a POCSAG1200 -f alpha /dev/stdin".
Any suggestions?
Thank you in advance...
